RIGHT TO VILLIAM KAP- S A D I R O N SPECIFICATION forming part ofLetters Patent No. 406,943, dated July 16, 1889.

Application tiled April 20, 1888. Serial No. 271,299. (No model.)

To all whom it may concern:

2e it known that we, SPARRow M. NIC/K- ERsoN and (f -xLvIN J. HOLMAN,citizens of the United States, and residents of Chicago, in the conntyofCook and State of Illinois, have invented certain new and usefulImprovements in Sad-Irons, of which the following' is a specification.

'lhis invention relates to improvements in sad-irons hea-ted internallyby means of Hainejets, and has for its objects an iron so constructed asto prevent the escape of the flame from the iron during the use thereof,and also the breaking up and distribution of the anie, so as to promoteits heating effect upon the iron, and a more perfect combustion of thegases employed for heating the iron from its interior, and finally tomix the supply of gas to an iron previous to its discharge into theburner of said iron, whereby perfect combustion by the burner iscorrespondingly promoted. \Ve attain these objects by the devicesillustrated in the accompanying drawings, in which-A Figure l representsa central vertical seetion of a sad-iron embodying our invention, Fig.2,a horizontal section of the iron on line 2 2 of Fig. 3, and Fig. S acentral vertical se?.- tion of the iron.

Similar letters of reference indicate the saine parts in the severalfigures of the drawings.

Referring by letter to the accompanying drawings, A indicates the usualwooden handle, and I5 B the bail or supports thereof, the support 'lextending` downwardly a suitable distance to form a pivotal bearing forthe iron body, while the support B is shorter and extends at an obliqueangle from the handle, the outer end of which is formed into au eye C,in which is rigidly secured, by screwing or otherwise, one end of avertical pipe I),to the lower end of which and extending at rightanglesthereto is secured another pipe E, proj ecting toward the support l, andperforated, as shown, preferably on the under side there- Thisperforated pipe is closed at the end thereof and constitutes one bearingof the iron body F, one end of which bears thereon near the verticalpipe D, while the opposite end of said iron has cast thereon orotherwise rigidly secured thereto a trunnion G, which works through aneye in the lower end of the support B and constitutes the other bearingof the body, which is thus loosely journaled within the handle and freeto revolve on its bearings.

To the end of the trunnion G, projecting beyond the supports B, ispivotally secured a rod H, provided with a knob I on the end th ereof,an d constitu tin g the handle, by means of which the iron may berevolved upon its pivot, the said rod being adapted and arranged to beforced between opposing spring jaws or catches J, attached to thehandle-support B, so as to lock the iron in either of its adjustedpositions.

To the upper end of the pipe l), projecting beyond the eye C., issecured a nozzle constitilting an air-chamber K, perforated at L for theadmission of air, and with the nozzle is connected, byineans of aswi\'feljoint, a metal lic pipe M ,either straight or curved, as shown,to the opposite end of which is secured a rubber or other flexiblesupply-pipe N, through which gas is conducted to the iron, theperforations in the nozzle admitting sufficient atmospheric air for thepurposes of combustion, which mixes with the gas before its dischargeinto and ignition in the iron.

The swivel-connection between the supplypipe N and the iron enables afree movement of the iron in any direction without danger of twisting orbending the pipe and thereby cutting off the gas-supply, and the ironmay be used equally well at any point within the radiusofthesupply-pipe. ]esides,theconnection between the vfiexible supply-pipeand the iron is thereby effected at such a height above the articlesbeing ironed to greatly facilitate the work of the operator by holdingthe pipe always out of the way.

The principal feature of our invention, however, is the coi'istructionof the interior of the body of the iron, which walls have heretoforebeen made plain in hollowing out the interior thereof, so as to providea heatingspace for the burner; but practice has ,deinem strated thatwith an iron so constructed the heated air and products of combustionnot only pass quickly and directly out of the perforations a, formed inthe side Walls thereof, first toward one end and then toward the otheras the iron is moved back and forth, but frequently the jetllames Willissue through said perforations and burn both the hand of the operatorand the garment being ironed. In order to avoid this objection and atthe same time economize the heat, We have provided the body of the ironbetween each pair of perforations with vertical ribs b and horizontalribs c, projecting inwardly from the side Walls of the iron toward thecenter, leaving only sufficient roomV for the insertion of the burnerand the passage around it of the heated air and products of combustion.These ribs all tend to deiiect the flame-jets and obstruct the exit ofthe heated air and products of combustion, thehorizontal ribseifectually preventing the direct rising of the llames through and outof the upper sets of perforations, While the vertical ribs not onlymaterially aid the horizontal ribs in their function by making tortuouspassages for the exit of the products of combustion, but prevent directand insetting drafts from either side, occasioned by the rapid movementsof the iron, from acting on the `flame-jets and forcing them through theperforations in the iron.

Another important result is the saving of fuel effected by thisconstruction, due to the increased heating` capacity of the fuel, owingpartly to the detention of the products of combustion within the ironand partly to the increased radiating-surface furnished by thedei-lecting-ribs, and this saving is important foratwofold reason,iirst, because of the saving in fuel, and, second, the saving of thetime of the operator, because the iron will not have t0 be so oftenreversed.

Having described our invention, what We desire to secure by Let-tersPatent is l. A hollow internally-heated sad-iron having vertical ribs bprojecting from the side Walls and formed integral with the face of theiron, and perforations between said ribs, substantially as described.

2. A hollow internally-heated sad-iron provided With Vertical ribs Ziand horizontal ribs c, projecting from the side Walls of the iron, theVertical ribs being integral with the face of the iron, substantially asdescribed.
